A production-like environment requires a lot of RAM and ideally enterprise SSDs for
the index, as well as some additional terabytes of slower harddrives for storing crawl
data. It can be made to run on smaller hardware by limiting size of the index.
The system will definitely run on a 32 Gb machine, possibly smaller, but at that size it may not perform
very well as it relies on disk caching to be fast.
A local developer's deployment is possible with much smaller hardware (and index size).

The link database contains information about links,
such as their ID, their URL, their title, their description,
and so forth.
The link database is a sqlite file. The reason this information
is not in the MariaDB database is that this would make updates to
this information take effect in production immediately, even before
the information was searchable.
It is constructed by the [loading-process](../../processes/loading-process), and consumed
by the [search-service](../../services-core/search-service).

# Converting Models
Contains models shared by the [converting-process](../../processes/converting-process/) and
[loading-process](../../processes/loading-process/).
## Design
The two processes communicate through a file-based protocol. The converter serializes [instructions](src/main/java/nu/marginalia/converting/instruction/Instruction.java)
to file, which are deserialized by the loader and fed into an [instructions](src/main/java/nu/marginalia/converting/instruction/Interpreter.java).
The instructions implement a visitor pattern.
Conceptually the pattern can be thought of a bit like remote function calls over file,
or a crude instructions-based programming language.
This
```java
producer.foo("cat");
producer.bar("milk", "eggs", "bread");
```
translates through this paradigm, to this:
```
(producer)
writeInstruction(DoFoo("Cat"))
writeInstruction(DoBar("Milk", "Eggs", "Bread"))
(consumer)
while read instruction:
interpreter.apply(instruction)
(Interpreter)
doFoo(animal):
...
doBar(ingredients):
...
(doFoo)
DoFoo(animal):
apply(interpreter):
interpreter.foo(animal)
(doBar)
DoBar(ingredients):
apply(interpreter):
interpreter.bar(ingredients)
```

The processed-data package contains models and logic for
reading and writing parquet files with the output from the
[converting-process](../../processes/converting-process).
Main models:
* [DocumentRecord](src/main/java/nu/marginalia/model/processed/DocumentRecord.java)
* * [DocumentRecordKeywordsProjection](src/main/java/nu/marginalia/model/processed/DocumentRecordKeywordsProjection.java)
* * [DocumentRecordMetadataProjection](src/main/java/nu/marginalia/model/processed/DocumentRecordMetadataProjection.java)
* [DomainLinkRecord](src/main/java/nu/marginalia/model/processed/DomainLinkRecord.java)
* [DomainRecord](src/main/java/nu/marginalia/model/processed/DomainRecord.java)
Since parquet is a column based format, some of the readable models are projections
that only read parts of the input file.
